Fig. 3-5 illustrate a scribing apparatus 100 according to one embodiment of the present disclosure at different viewing angles. The scribing device 100 is used for scribing lines with a predetermined pattern on a large glass original sheet so that a subsequent breaking device can break the glass along the predetermined lines. In an embodiment of the present disclosure, the scribing apparatus 100 draws two lines (including straight lines and curved lines) in different directions.

The scoring device 100 basically includes an optional glass transport mechanism, a cutter, and a scoring drive mechanism that drives the cutter to score two lines in different directions. The scribing driving mechanism can comprise a Y-axis scribing driving mechanism, an X-axis scribing driving mechanism, a Z-axis scribing driving mechanism and a cutter head rotating driving mechanism. As shown in fig. 3, the glass conveying direction is set to the Y-axis direction. The X-axis direction is defined as another lateral direction perpendicular to the Y-axis. The Z axis is vertical to both the X axis and the Y axis.

The glass conveying mechanism includes a driven roller 101, a stage 102, a conveying belt 103, a driving roller 124, and a driving motor (not shown). The platform 102 is fixedly mounted to the frame. The driven roller 101 and the driving roller 124 are rotatably mounted on the frame at a certain distance. The conveyor belt 103 is looped around the driven roller 101, the table 102, and the drive roller 124. When the driving roller 124 is driven by the motor to rotate, the conveying belt 103 is driven to roll, and the driven roller 101 is driven to rotate. As shown in fig. 3, when the drive roller 124 rotates, the glass a placed on the conveyor belt 103 can be conveyed from the sheet-feeding position to the scribing position in the direction of the illustrated arrow.

The Y-axis scribing driving mechanism is arranged on one side close to the glass scribing position and is used for driving the rest driving mechanism and the cutter to move along the Y-axis direction. The Y-axis scribing driving mechanism may include at least one first lead screw assembly, and the first lead screw assembly is composed of a first lead screw rear base 104, a first linear guide rail assembly 105, a first lead screw assembly 119, a first nut base 120, a first motor base 121, a first motor 122, and a first lead screw front base 123. Wherein, the first screw rear seat 104 and the first screw front seat 123 are fixedly arranged on the frame, the first linear guide rail assembly 105 is parallel to the glass conveying direction and arranged outside the conveyor belt 103 and the platform 102, and the height of the first linear guide rail assembly 105 is basically the same as that of the conveyor belt 103. A support frame 106 supporting the tool is slidably mounted on the first linear guide assembly 105 by means of a slide. The first lead screw assembly 119 is parallel to the first linear guide assembly 105, and is provided with a first lead screw rear seat 104 at the rear end and a first lead screw front seat 123 at the front end. It should be noted that the front-back direction mentioned here refers to the glass conveyance direction.

A first motor 122 is mounted to the front end of the first linear guide assembly 105 with a first motor mount 121. The first nut base 120 moves along the first lead screw assembly 119 under the driving of the first motor 122, and simultaneously drives the support frame 106 to slide along the first linear guide rail assembly 105, so as to realize the movement of the tool in the Y-axis direction. That is, the first lead screw assembly 119 and its related mounting structure constitute a fixed portion of the Y-axis scribing driving mechanism, and the first nut block 120, the slider, and the like, which are slidable on the first lead screw assembly 119, constitute a sliding portion of the Y-axis scribing driving mechanism.

In some embodiments of the present disclosure, the Y-axis scribing drive mechanism comprises two sets of the first lead screw assemblies described above. Two sets of first screw rod assemblies are respectively arranged at two sides of the conveyor belt 103. The two sets of first screw assemblies move synchronously, thereby driving the two ends of the support frame 106 to move synchronously along the Y-axis direction.

Bit cylinder 115 may be raised and lowered to control the depth of the scribe of bit 116.

The cutter head rotation driving mechanism is used for driving the cutter head to rotate around the vertical shaft. The bit rotary drive mechanism generally includes a bit motor 118 and a bit belt 117. The tool bit motor 118 is installed on the tool bit seat 113, and a first belt pulley is provided on the output end thereof. A second belt pulley is arranged at the output shaft of the cutter head cylinder 115. A cutter belt 117 is wound around the first pulley and the second pulley. The output shaft of the cutter head cylinder 115 is driven to rotate around the axis thereof by the rotation of the cutter head belt 117, and then the cutter point at the bottom is driven to rotate around the vertical axis. The cutter head rotation driving mechanism functions to control the cutting direction of the scribing cutter of the cutter head 116 to be the same as the tangential direction of the drawn curve or straight line.

In the embodiment of the disclosure, the Y-axis scribing driving mechanism, the X-axis scribing driving mechanism and the tool bit rotation driving mechanism are subjected to interpolation motion control by the controller so as to meet the requirements of longitudinal and transverse scribing and can scribe a curve shape. The first motor 122, the second motor 127, and the cutting head motor 118 are all servo motors. The cutter head cylinder 115 is a high-precision cylinder, and controls the pressure of the cutter head during scribing by adjusting the air inlet pressure so as to ensure a certain scribing depth. The upper surface of the conveyor belt 103 is divided into two areas, i.e., a sheet-on-glass area and a scribing area, to which glass is fed when scribing is required. The bit lift cylinder 110 is an adjustable stroke cylinder to facilitate the up and down displacement of the bit 116.

The construction and operation of the large lift screw assembly 219 and the large lift screw base 215 are similar to the first screw assembly described above. To avoid repetition, a detailed description thereof is omitted. The large elevator motor 218 drives the large elevator screw assembly 219 to drive the large elevator plate 213 to move along the Z-axis direction relative to the large guide rail plate 206.

The large glass suction mechanism is used for sucking the large glass in the scribing area and transferring the glass to the area where the supporting plate 208 is located in cooperation with other components, and is also used for feeding the glass into the large breaking device 300. The large glass suction mechanism may include a support bar 207, a vacuum chuck 209, a chuck support piece 210, a chuck support screw 211, and a chuck support bar 212.

In some embodiments of the disclosure, since the production time of glass scribing is much shorter than the glass breaking time, two sets of large-piece transferring devices and breaking devices are symmetrically arranged on two sides of the scribing device, thereby improving the production efficiency of the whole machine. Each small piece of glass corresponds to one vacuum chuck, and the position of the chuck can be adjusted at will in the X-axis and the Y-axis so as to adapt to small pieces of glass with different specifications. The bottom surfaces of all the suckers are on the same plane, so that the glass can be firmly adsorbed.

Two break-off bar actuators 306 and optionally a scale marker strip 311 are mounted on the frame. The breaking-off bar support 307 and optionally the pointer 310 are mounted on the breaking-off bar actuator 306. Both ends of the breaking-off bar 308 are supported by two breaking-off bar support frames 307, respectively. The breaking-off bar actuator 306 drives the breaking-off bar support 307 and the breaking-off bar 308 thereon to move up and down in directions indicated by double arrows in fig. 9. The breaking bars 308 may employ cylindrical rollers. The severing bar 308 is at a height close to the height of the pallet 208 and immediately adjacent to the end of the pallet 208. The supporting plate 208 is provided with a notch at a position close to the two breaking-off bar actuators 306 to provide a space through which the breaking-off bar actuators 306 pass.

In an embodiment of the present disclosure, the bulk glass press breaking mechanism presses breaks glass by swinging.

Since the two sets of snap-off bar mounting assemblies are similar in structure, only the structure of one set (the left portion shown in fig. 8) will be described in detail below, and the structure of the other side (the right side of fig. 8) is arranged in a symmetrical fashion to the described snap-off bar mounting assembly. The support block 303 may be attached to the support bar 207 or the large lift plate 213 of the large transfer device 200, so that the glass breaking mechanism can move synchronously with the large glass suction mechanism of the large transfer device 200.

The breaking-off cylinder 304 is fixedly mounted on the support block 303, the output end of the breaking-off cylinder 304 is provided with a pressure wheel seat 305, and the breaking-off cylinder 304 can drive the pressure wheel seat 305 to move up and down along the Z-axis.

Two guide wheels 312 are rollably disposed in the circular arc guide groove C. Each guide wheel 312 may include a protruding shaft extending toward the support block 303 on the opposite side. Each protruding shaft is mounted on the breaking bar seat 301. Referring to fig. 10B, the breaking bar holder 301 may employ a support member having an approximately U-shape. The U-shaped support includes opposing first and second legs and a connecting portion connecting the first and second legs. The protruding shaft of guide wheel 312 is mounted on the first leg. The second leg is fixedly connected with a breaking-off strip 309. The first leg part is also provided with an open slot D which generally extends along the X-axis direction, and the open slot D can be a straight slot. The puck 302 is disposed in the open groove D. When the breaking-off cylinder 304 is activated to drive the pinch roller base 305 to move downwards, the pinch roller base 305 drives the pinch roller 302 mounted thereon to move downwards. The motion of the pressing wheel 302 in the opening groove D forces the breaking-off bar seat 301 and the two guide wheels 312 thereon to rotate around the central axis of the arc guide groove C by an angle. That is, the two guide wheels 312 slide in the arc guide groove C for a certain arc length in the direction indicated by the arc arrow in fig. 10B. The rotation of the breaking bar holder 301 causes the breaking bars 309 to deflect (as indicated by the arc-shaped arrows in fig. 9), thereby pressing the glass downward.

In some embodiments of the present disclosure, at least one dust suction port B connected to a dust suction fan is provided on the breaking-off bar 309.

The controller may be a single controller that controls all of the motors and the suction mechanisms, or may be a plurality of controllers that control the respective motors and the suction mechanisms, respectively.

The workflow of the fully automatic film opening system according to the present disclosure is described below. The glass a is placed at the loading position shown in fig. 3, the glass scribe shape data is introduced into the controller, and the controller is started after confirming that the cutter head 116 is at the working home position. The controller gives an instruction to move the cutter head 116 to the marking starting position, then the cutter head lifting cylinder 110 descends with the cutter head cylinder 115 in sequence to press the cutter head 116 on the upper surface of the glass A, and the marking depth is controlled by the cutter head cylinder 115. If only the Y-axis scribing driving mechanism or the X-axis scribing driving mechanism works independently, only one straight line can be scribed, and the two mechanisms can scribe a curve by interpolation movement. The cutter head rotation driving mechanism functions to control the cutting direction of the scribing cutter of the cutter head 116 to be the same as the tangential direction of the drawn curve or straight line.

After the glass A is scribed, the large glass adsorption mechanism is lifted by the large lifting mechanism, and then the large glass adsorption mechanism is conveyed to the position right above the scribing area by the large transfer mechanism. Then a large glass adsorption mechanism is placed on the upper surface of the marked glass by a large lifting mechanism, and a vacuum machine is started to adsorb the glass. Then, the glass is lifted and transferred to the placing position corresponding to the breaking-off device 300, and the glass is placed on the glass pallet 208, and then the vacuum machine is turned off, and the glass adsorption mechanism is lifted. Subsequently, the large transfer mechanism moves a distance corresponding to the width of one small glass sheet in the direction of the scribing apparatus 100. Thereafter, the large glass suction mechanism drops again and the vacuum machine is started to suck and lift the glass to move a distance of a small glass width in a direction close to the large breaking device 300, at which time the line closest to the large breaking device 300 is right above the breaking bar 308, and then the glass is lowered and released. The large glass suction mechanism is raised again and moved inward (in a direction away from the large breaking-off device 300) by the width distance of a small piece of glass, at which time the breaking-off bars 309 are positioned directly above the wire and breaking-off rods 308. When the glass is broken, the glass support mechanism is at the lowest position, and at this time, the large piece transfer device 200 has conveyed the outermost long glass of the glass a to the upper position of the glass support mechanism, and the scribe mark should be right above the central axis of the breaking bar 308. Subsequently, the breaking-off rod actuator 306 pushes the breaking-off rod 308 to rise to slightly lift the glass a from below, and then the breaking-off cylinder 304 acts to drive the pressing wheel 302 to move downwards, so that the breaking-off bar seat 301 is forced to rotate around the central axis of the arc guide groove C by an angle. The rotation of the breaking-off bar holder 301 causes the breaking-off bars 309 to deflect, and the deflection motion causes one side of the breaking-off bars 309 to press against the glass, and since the lower surface of the glass has been supported by the breaking-off bars 308, the glass is broken along the scratches under pressure, thereby obtaining a long glass including a plurality of small pieces. After the outermost glass is broken off by the large-piece breaking device 300, the large-piece glass adsorption mechanism descends again to move the glass outward by the distance of one piece of glass, and the process is repeated until all the glass is broken off completely. The last piece of glass may be transferred by the suction mechanism directly onto the tab substrate 414. In addition, the operation frequency of the large piece breaking device 300 should match the operation of the small piece breaking device 500.

The long glass ribbon cut off by the large-piece cutting device 300 is placed on the small-piece base 414. And the small piece X-axis driving mechanism sends the small piece adsorption mechanism to the position above the broken long glass strip, and then the small piece Z-axis driving mechanism descends to attach the small piece suction cup 415 to the upper surface of the glass and starts a vacuum machine to adsorb the long glass strip. The die Z-axis drive mechanism then ascends. The X-axis drive mechanism for the pieces is reset and the glass strip is transferred to the breaking position for the pieces, and then the Z-axis drive mechanism for the pieces is lowered again to place the glass strip on the bottom plate 414 for the pieces and the vacuum is turned off. Then the small piece Z-axis driving mechanism drives the small piece adsorption mechanism to ascend again and move backwards (i.e. in the direction away from the small piece breaking-off device 500) by the distance of the length dimension of the small piece of glass under the action of the small piece Y-axis driving mechanism. Then the small piece Z-axis driving mechanism drives the small piece adsorption mechanism to descend again to adsorb the glass and ascend, and the small piece Y-axis driving mechanism moves forwards by the distance of the length size of the small piece of glass. Thereafter, the chip Z-axis drive mechanism again drives the chip pick-up mechanism down and drops the glass onto the chip floor 414. At this time, the foremost small glass pieces of the long glass strips enter the breaking station of the small glass piece breaking device 500. When the small pieces are broken, it is confirmed that the small piece transfer device 400 sends the foremost small piece of glass on the glass strip to the small piece breaking station and the breaking score line of the glass surface is located right above the central axis of the small piece breaking bar 516. Then, the small piece supporting mechanism starts to operate, and the small piece lower actuator 512 lifts the small piece breaking bar 516 via the small piece breaking bar supporting bar 513 to lift the glass from below. Next, the piece breaking mechanism is operated, and the piece upper actuator 509 moves down all the components mounted thereon to make the lower surface of the piece breaking bar 503 abut on the upper surface of the glass. And then a small piece breaking cylinder 507 is started to enable a small piece breaking bar 503 to generate deflection action to press and break the glass along the surface scribing line. And then the small piece supporting mechanism and the small piece breaking mechanism are reset completely. The crushed glass chips are just landed on the chip conveyor 502 of the chip conveyor and conveyed to the next process. And repeating the process of breaking off the small glass pieces until the whole glass piece is broken into small pieces. The last piece of glass can be transferred to the piece conveyor 502 using the piece transfer apparatus 400.
